Abstract:
The title compound, C14H14N2S2, was obtained by transmetallation of 2,2'-bis-(tri-methyl-stann-yl)azo-benzene with methyl lithium, and subsequent quenching with dimethyl di-sulfide. The asymmetric unit comprises two half-mol-ecules, the other halves being completed by inversion symmetry at the midpoint of the azo group. The two mol-ecules show only slight differences with respect to N=N, S-N and aromatic C=C bonds or angles. Hirshfeld surface analysis reveals that except for one weak H⋯S inter-action, inter-molecular inter-actions are dominated by van der Waals forces only.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
